The new EPCOS R159 and D5107 from TDK are front-end modules for satellite navigation systems that enable the coexistence of cellular, WLAN, Bluetooth and satellite navigation services on the same antenna. The R159 supports GPS and GLONASS (1575 MHz to 1605 MHz) and combines a low-noise amplifier (LNA) and low-loss SAW extractor. The D5107 supports GPS, GLONASS and BeiDou, combining a SAW bandpass filter, matching and linearity enhancing circuits, and an LNA with a very low noise figure and supply current. Both devices come in a 2,5 x 2,5 x 0,8 mm package and the D5107’s metal plating protects the GPS receive path from interference by spurious signals (received via air interface) into the GPS receiver chain.
